Sinking a CV after being forced to autoswitch is dirty, unless that CV is being used by the enemy or has been spotted by someone on the team you switched to. Where are these naval damage numbers coming from? I don't see it tracked on the scores page.
Its especially dirty if you were the one commanding it into its position.
Alas, it is the life of an autoswitcher, many times I'll be attacking a base and all it needs is troops, I'll land and then get switched to the team I was attacking. Often times I defend the base because thats what I would normally do if it was under attack. I'm not going to ignore that the base is in danger just because i'm the one that put it in danger. You don't make many friends in those cases though, as they see you were just helping, but now they are dieing to you.
